To all whom it may concern;

Be it known that I, RALPH G. J AGKSON, a

One object of my invention is to design the machine so that traveling tripping blocks will actuate the mechanism for releasing the printing devices.

A further object of the invention is to arrange the carriers for the tripping blocks so that the blocks can be shifted in order to hold up certain printing blocks and to allow others to make impressions.

A still further object ofthe invention is to design the mechanism so that an operator at the feed end of the machine can so shift the tripping blocks that certain portions of the fabric can be passing through the machine without being printed upon.

Still another object of the invention is to reduce the waste, due to imperfections in the material, by adjusting the printing blocks so that a portion of the material can be cut.

out and a rug of a different size, from that for which the machine is set, can be printed. Heretofore, if an imperfection occurred in the material the rug had to be printed and Figk is a sectional plan view on the line 33, Fig. 1;

Fig. 4 is a diagrammaticside view of the entire machine Fig. 5 is a plan view of a portion of the feed end of the machine;

1 is the frame of a fiat block printing machine 2 are the printing block carriers.

-3 are the endless tapes passing around' wheels 4, at each end of the machine, and

operated by any suitable mechanism. The block carriers are raised by a cam 22 of the ordinary type. 5 is a table extending the full len th of the machine between the tapes upon w ich the material to be printed travel's. The tapes have pins 6 which engage the material a and feed it intermittently through the machine. The material is brought to the machine in a roll, as at 6, Fig. 4:, and

passes through the machine, and, in the present instance, down an inclined plane 7 atthe discharge end of the machine from which it is introducedinto a" drier of any suitable construction. At each block carrier is a'latch 8, which engages the carrier This latch and holds it up out ofaction. is pivoted at 9 to the frame of the machine and is actuated by my improved mechanism,

.- any of the types now in common use.

Located atone side of the machine are brackets 10, which carry an endless band, or

12 are guides forming three divisions 13 13 and 13, for the tripping blocks 13, which arearranged' in 18" units,

in the present instance, as each printing block is 18" wide. The tripping blocks are made in three sections, which are pivotally connected so as top ass around the wheels at each end of the machine. In the present instance, there is a series of pivot rods 23 on which .the block sections are mounted and these pivot rods are attached to the'endless band 11 and when the blocks are shifted laterally the pivot rods guide them so that theEy will be held in proper alignment.

ch latch 8 has an arm 14 through which extends a vertical pin 19. A spring 21 is located in a pocket in the arm 14 of the latch 8 and bears against a projection 20 on the frame 1, Fig. 2. Projecting laterally from the pin 19 is a pin 15, which carries a roller 17-. The outer end of the pin 15 is located in a slot in a rib 16 projecting from the i and at the same time holds the latch 8 in When a rug of a given length is'to be printed on this machine, the trippin blocks are solocated-that certain blocks Wi l'travel in one guideway and others will travel in the otherguideways. The rollers 17 on the ine with any of the three guideways. This arrangement enables rugs to be rinted having borders and I find that tlree sets of blocks are necessary, one for the central sec-' tions :1: of the ru having a section of a border at each si e of the end sections 3 and a, each having a continuation of the side borders and having an end border.=

Three different sets of blocks are necessary. Theseblocks are duplicated, according to the a number of colors in which the rug lsto be printed.

tripping blocks are so arranged that they will release the printing blocks at the proper 1311118 to prlnt portions of the fabric so that If a rug, such as illustrated in Fig. 6, is to be printed, then for each impression of the right and left border blocks there will be four impressions of the center blocks in. The

each rug printed will be of a given length, sa 108 ,if the printing blocks be 18 wlde. n the event of an imperfection, such'as a tear, occurring in the fabric, the operator at the feed end of the machine will see the tear as it comes from the roll e, and will so adjust the trippingblocks in the ways as to skip the imperfectlon and to print a .rug border in advance of the imperfection, making a rug smaller than thestandard size be e fabric immediately a ter the imperfection is passed. The rug of this border may be of the standard length, or may be less, according to the character of the imperfection discarded.

7 While I have shown three divisions, or channels, for the tripping blocks, it will be understood that any number may be used without departing from the main feature .of the invention. I

In the drawings, 1' have shown only one side of a lockprinting machine. I have shown the pivot rod 9 extending towards the opposite side of the machine as in Fi 2 and 3. There is a latch, similar to the atch -8, on the opposite side of the machine in order to hold the printing block carriers properly in the raised position.

I for instance, there are four sets of printing blocks, each having a different deins 15 can ,be adjusted so as to be brought in printed, and also printin a rug border on t sign, it will be necessary to have an'additional division, or channel. When there are no imperfections in the fabric being printed, the tripping blocks remain in the position in which they were originally set. It is only when there is an imperfection, or when it is desired to print a ru of a different size, that the tripping bloc s are shifted.

I claim:

1. The combination in a block printing machine, ofa frame; a series of block carriers; means for actuating the block carriers; means for intermittently feeding material through the machine; a latch for holding each block carrier outrof action; means extending longitudinally of the machine and traveling at the same rateof speed as the material; and tripping blocks carried by said means; said blocks being laterally adjustable.

L2. The combination in a block printing machine, of a frame; reciprocating block carriers mounted on the frame; printing blocks mounted on the carriers; a latch for holding each block carrier out of action; means for intermittently feeding material to be printed through the machine; an endless carrier on one side of the machine; means for driving the carrier intermittently and at the same speed as the material being printed; and a series of tripping blocks mounted on the carrier and arranged to be adjusted laterally in one of three positions, the latch having arms arranged to be actuated by certain blocks.

3. The combination in a block' printing machine, of a frame; reciprocating block carriers spaced a given distance apart;

means for operating the block carriers; means for intermittently feeding material through the machine; a pivoted latch at each block carrier; springs for retaining the latches in engagement with the block carriers; a pin engaging the latch and having rollers adjustably mounted thereon; and an endless carrier travellng'at the same speed as the material being printed and having laterally adjustable tripping blocks thereon arranged to be shifted in alignment with certain rollers for actuating the latches.

4. The combination in 'a block printing machine, of a frame; a series of block carriers thereon; means for actuating the block carriers; means for intermittently feeding material through themachine; a latch for holding each block carrier out of action, each latch. having an, arm; a spring bearing against said arm and tending to hold the -latch in engagement with the block carrier;

and means for traversing said blocks at the same speed as the material to be printed.

5. The combination in a block printing machine, of a frame; reciprocating block carriers spaced a given distance apart; means for operating the block carriers; means for intermittently feeding material through the machine; latches for holding the block carriers out of action; an endless car- 10 rier at one side of the machine; means for moving the carrier intermittently and at the same speed. as the material being printed;a series of cross bars and tripping blocks pivotally mounted onthe cross bars, said blocks being made in sections and capable of being moved laterally; and longitudinal guides for retaining the tripping blocks in a givenposition so as to actuate certain latches.
